Validate Your Strategies with a Prototype
At this point in your design process, you should develop and test a prototype because you don't know yet whether the measurement and instructional strategies will help your learners master the performance objectives. Your design will remain a prototype until you have proven to yourself and your client that it actually does what it is intended to do.
This chapter shows you how to build a prototype. It also explains the Learner Tryout phase of the design process (Figure 7.1) and shows you why formative evaluation is like an insurance policy for instructional design.
